Why are surgical instruments in hospitals sterilized in an autoclave?

The rate of diffusion of a gas is directly proportional to which of the following?

Which of the following relations is true based on the partial pressure and mole fraction?

$A$ gaseous mixture was prepared by taking equal moles of $CO$ and $N_2$. If the total pressure of the mixture was found to be $1 \ atm$,the partial pressure of the nitrogen $(N_2)$ in the mixture is ............ $atm$.

$80 \, mL$ of $O_2$ takes $2$ minutes to pass through a hole. What volume of $SO_2$ will pass through the same hole in $3$ minutes?

$A$ $10 \ L$ vessel contains $1 \ mole$ of an ideal gas with pressure of $P \ atm$ and temperature of $T \ K$. The vessel is divided into two equal parts. The pressure (in $atm$) and temperature (in $K$) in each part is respectively:
